The Controllerfront panel indicators and keys are shown in Figure 1-1 Front Panel Controls and AVAILABLEA fter the controller has performed its power-up self-test (during which, if theFunction key is held down during power-up, the current controller firmwarerevision is displayed), the initial displays appear.
3 The available displays aredependent upon (a) whether the controller has been configured for SingleSetpoint operation or Dual Setpoint operation and (b) the setting of the SetpointStrategy parameter in Set Up Setpoint OperationIn single setpoint operation, the available displays Setpoint OperationIn dual setpoint operation, the available displays THE SETPOINT/SETPOINT RAMP RATEThe setpoint/setpoint ramp rate (whichever is selected - see previously) may beadjusted using the Raise/Lower keys. The ramp rate may be adkusted in the range 1 to 9999. Any attempt to increase the ramp rate value beyond 9999 will causethe upper display to go blank and setpoint ramping to be switched OFF.
4 Setpointramping can be resumed by decreasing the ramp rate value to 9999 or STATUS DISPLAYIf one or more of the controller s alarms is (are) active, the alarm status display isincluded in the available display sequence. The Alarm Status display is selectedby depressing the Function key repeatedly until the display appears (see Figure1-2). DISPLAYSThe upper display will indicate ifthe process variable is higherthan the input scale maximumlimit (over-range), or lower thanthe input scale minimum limit(under-range) as shown on BREAK INDICATIONIf a break is detected in the sensor circuit, the upper display shows:The reaction of the outputs and alarms to a detected sensor break is dependentupon the input type and is defined in Appendix CONTROL MODEIf selection of manual Control Mode is enabled, the manual Control Mode maybe entered (via a bumpless transfer) by depressing the Auto/ manual key.
5 The SETindicator will then flash continuously whilst the controller is in manual ControlMode. The output power will then be displayed and may be adjusted with theRaise/Lower return can be made to Automatic Control Mode (via abumpless transfer) by simply depressing the Auto/ manual key again, which causes the usual process variable display to 1-2 Alarm Status FACILITYThis facility may be used to set the controller s PID parameters to values which areapproximately correct, in order to provide a base from which the Self-Tune facilitymay subsequently optimise tuning. Pre-Tune may be engaged (and subsequentlydis-engaged) as follows:NOTE: The Pre-Tune facility will not engage if (a) the setpoint is currentlyramping, (b) the process variable is within 5% of input span of the setpoint,or (c) an erroneous key sequence is Pre-Tune is a single-shot operation, it will automatically dis-engageitself once the operation is FACILITYThis facility is be used to optimise tuning whilst the controller is operating.

To clear this display, simply alter the value/setting of any Set Up Mode parameter (see below). UP MODE PARAMETERSThe parameter sequence for view/adjustment in Set Up Mode is shown in Table2-1.
8 Use the Function key to step through the parameters. In each case, thelegend will be shown in the lower display and the current value/setting will beshown in the upper display. The value/setting may be altered using theRaise/Lower keys. A detailed description of each of these parameters is given inthe following Filter Time ConstantThe controller input is equipped with a digital filter which is used to filter out anyextraneous impulses on the process variable. This filtered PV is used for allPV-dependent functions (control, alarms etc.).CAUTION: If this parameter value is set excessively high, the control qualitymay be significantly impaired.
9 The value chosen should be sufficientlylarge to attenuate stray noise on the process variable signal but no Variable OffsetThis parameter is used to modify the actual process variable value (measured atthe controller s input terminals) in the following manner:Offset PV value = Actual PV value + Process Variable Offset CONTROLLERS fitted with a linear input, the displayed process variable value islimited by Scale Range Maximum (see Subsection ) and Scale RangeMinimum (see Subsection ). The offset process variable value is used for allPV-dependent functions (control, display, alarm, recorder output etc.)
10 NOTE: This parameter value should be chosen with care. Anyadjustment to this parameter is, in effect, a calibration application of values to this parameter could lead to thedisplayed process variable value bearing no meaningfulrelationship to the actual process variable value. There is no frontpanel indication when this parameter is in effect ( has been setto a non-zero value).O054-22-2591252-3O054-259125 ParameterLegendAdjustment RangeDefault ValueDigital Filter Time ConstantOFF, to secs. sec. secondsProcess Variable Offset Span of Controller0 Output Power0 to 100%Read onlyOutput Power 2 50 to 100%Read onlyProportional Band (ON/OFF control) of input Band 2 15, (ON/OFF control) of input (Integral Time Const.)
